In Windows, Blender folder not in Start Menu for all users?
I don't know much about Blender's installation routine since I use Linux for 3D modeling for stability reasons (and regardless of the OS I tend to use the zipped version), but recently there was a post of someone who claimed that it's exactly the other way round for 2.77b. 

Regarding you "is it normal" question - as a former IT admin I'd say, if a software runs properly and the only issue is that some icons that are not "in place", it's normal (aka "happens every day"). Just move the Icons over to the "all users menu folder" and it's fixed.

If this answers your question, please mark it as accepted.
